Now, I'm dead excited about all this wave surfing and the like, but last time I was here my natural reaction was to think pattern matcher. So, I'm gonna build what I wanted to in the first place, a pattern matcher, to get back into the swing of things, and see where it goes from there...

now my idea for one, first draft, and not a great departure from the norm, is roughly

record absoloute movements of E. IE; subtract my movement from changes to find just what E did.

match recent pattern of movement against previous history.

Play it forward, but rotate it all based offset from E's current heading...?
